LVT shrinking

hi guys, we fitted amtico form on jumpax 2 years ago on jumpax as the client was requesting soundproofing in his flat. I've just been contacted to say the Amtico has started to open up in front off his bi fold windows. it was all fitted on HT glue wet with plenty of expansion on the jumpax. anybody come across this before/ have solution on how to resolve this?
Im thinking that jumpax wasn't the best idea but with its soundproofing qualities felt like it was the best option at the time?
TIA

 

What HT was it

If it was Amtico’s own it’s terrible

Who makes that? Once upon a time it was bostiks

 

What glue would you recommend?

 

Ke66. Go in wet!

 

Personally lvt in the sun I wouldn’t guarantee any glue but so far Uzin kt 66 and fball f49 hybrid ps seem to work best

As it’s at the bi fold doors it could be some moisture getting into the jumpax which will rot it.

 

Ke66 isn’t recommended for direct solar gain anymore....unsure why you’d use it in a ht area with sunlight if it’s not deemed recommended anymore, f48 is amtico the is f ball.

 

That makes sense f48 is rubbish

Going forward then what you recommend for direct solar gain?

 

I’ve just been to look at it and it was actually HT extra (pink glue)

 

No that pink stuff is terrible. Seen LVT shrink on that around bifold doors. The grab is naff

F48+ I thought was the pink stuff, never heard Anything good about it

 

Uzin will say k68, f ball will start saying f73, murexin say d495 or d499
